Displaying 0 Values in Syncfusion Presentation Stacked 100 Bar Chart

[Yasmin Eldokany]

Hello,

Is there a way to plot 0 values in stacked 100 bar charts, like the third bar in the following sample image?

I'm using the .Net Core Syncfusion Presentation package and the chart doesn't display a bar by default for 0 values, like the below image:

Thank you!

Hello,

The presentation is generated entirely from code, kindly check the below code snippet:

        //Creates a Presentation instance

        IPresentation pptxDoc = Presentation.Create();

        // Create an instance of Presentation Renderer for converting chart to image

        pptxDoc.PresentationRenderer = new PresentationRenderer();

        //Adds a blank slide to the Presentation

        ISlide slide = pptxDoc.Slides.Add(SlideLayoutType.Blank);

        //Adds chart to the slide with position and size

        IPresentationChart chart = slide.Charts.AddChart(100, 10, 700, 500);

        //Specifies the chart title

        chart.ChartTitle = "Sales Analysis";

        //Sets chart data - Row1

        chart.ChartData.SetValue(1, 2, "Jan");

        chart.ChartData.SetValue(1, 3, "Feb");

        chart.ChartData.SetValue(1, 4, "March");

        //Sets chart data - Row2

        chart.ChartData.SetValue(2, 1, 2010);

        chart.ChartData.SetValue(2, 2, 0);

        chart.ChartData.SetValue(2, 3, 0);

        chart.ChartData.SetValue(2, 4, 0);

        //Sets chart data - Row3

        chart.ChartData.SetValue(3, 1, 2011);

        chart.ChartData.SetValue(3, 2, 800);

        chart.ChartData.SetValue(3, 3, 700);

        chart.ChartData.SetValue(3, 4, 600);

        //Sets chart data - Row4

        chart.ChartData.SetValue(4, 1, 2012);

        chart.ChartData.SetValue(4, 2, 600);

        chart.ChartData.SetValue(4, 3, 700);

        chart.ChartData.SetValue(4, 4, 800);

        //Sets the data range of the category axis

        chart.PrimaryCategoryAxis.CategoryLabels = chart.ChartData[2, 1, 4, 1];

        //Creates a new chart series with the name

        IOfficeChartSerie seriesJan = chart.Series.Add("Jan");

        //Sets the data range of chart series – start row, start column, end row, end column

        seriesJan.Values = chart.ChartData[2, 2, 4, 2];

        //Creates a new chart series with the name

        IOfficeChartSerie seriesFeb = chart.Series.Add("Feb");

        //Sets the data range of chart series – start row, start column, end row, end column

        seriesFeb.Values = chart.ChartData[2, 3, 4, 3];

        //Creates a new chart series with the name

        IOfficeChartSerie seriesMarch = chart.Series.Add("March");

        //Sets the data range of chart series – start row, start column, end row, end column

        seriesMarch.Values = chart.ChartData[2, 4, 4, 4];

        //Specifies the chart type

        chart.ChartType = OfficeChartType.Bar_Stacked_100;

        using (var stream = new MemoryStream())

        {

            pptxDoc.PresentationRenderer.ConvertToImage(chart, stream);

            slide.Shapes.AddPicture(stream, 100, 10, 700, 500);

        }

        //Save the PowerPoint file

        pptxDoc.Save("Output.pptx");

        //Close the PowerPoint instance

        pptxDoc.Close();

This generates the following chart image, how can I get the 0 bars to display like the above image:

I'm using the latest Syncfusion.Presentation.Net.Core and Syncfusion.PresentationRenderer.Net.Core nuget package versions (v19.1.0.57).

Hi Yasmin,

Thank you for sharing us the details.

On further analyzing, we have found in Microsoft PowerPoint application, series of the chart not displayed when chart data value is zero. Essential Presentation does the same. It is not an issue which is behavior of chart in the Microsoft PowerPoint application.

Please let us know if you have any other questions.
